BP340-46 | BP340 Near-UV Bandpass Filter

The MidOpt BP340-46 UV Bandpass filters are an economical yet highly transmissive/high contrast alternative to far more costly thin film interference filters. The design of this filter combines rugged dielectric coatings and absorptive filter glass to ensure a highly stable passband and excellent out-of-band blocking, even when used in conjunction with very short focal length lenses. The Midwest Optical Systems manufacturing program also makes it possible to supply larger custom shapes and sizes – up to 165mm square – within a matter of days. The BP340 finds use in UV fluorescence, forensic, scientific, multispectral, machine vision, sensing and other imaging applications.
